My invention relates -to metal Weather* strips of the type designed tobetacked along one longitudinal margin only. 'Weatherstrips of this typeare made of thin resilient metal with one longitudinal margin doubledback and bent at an oblique angle to the body of the strip to form anailing flange and With the opposite marginal portion beaded or ldoubledback to prevent puckering and adapt it for sliding contact, the nailingiange being tacked, for instance, to thev runway of a Window frame andthe free beaded edge bearing resiliently against the edge of the Windowsash.

' Metal Weatherstrips of this type are used extensively; but they areopen to the objection, that under certain conditions, they be- OCCHI'.

Fig. l is a cross-section of a metal Weatherstrip embodying myinvention, said strip being shown interposed between the meeting edgesof a frame member and the hinged or sliding closure member therefor; and

Fig. 2 isan isometric perspective of a portion of said strip.

The present Weatherstrip is made of thin resilient metal and comprises abody portion l and a nailing flange 2 along one edge there of, and abead or doubled back marginal portion 3 along the opposite edge adaptedfor sliding contact. As usual, the nailing flange is bent at an obliqueangle to the body of the strip, Aso that, when the nailing flange istacked flatwise to a frame A, the body of the strip will stand outobliquely relatively to` such fiange and frame, and bear resilientlyagainst the adjacent face of the closure member B for said fram-e.

In the ordinary resilient metal Weatherstrip of this type, the freeportion thereof,

yvhen exposed to a stid breeze` or high Wind, 1s likely to vibrate afterthe manner of a musical reed or membrane andemit an audible sound thatincreases in intensity Withthe velocity` of the Wind. Besides, suchWeather-` strip is usually made of such thin gagemetal that themechanical operations necessary to form the nailing flange and themarginal bead and particularly the operation of tacking the nailingflange in place are liable to produce such buckling and internalstresses in the metal as to leave the strip in a condition to produceconsiderable noise in response to the shifting of mechanical stressesthereon, such, for instance, as are due to high Wind.

According to the present invention, longitudinal corrugations 4 areformed in the 1niddle Or body portion of the strip and arrangedobliquely to the margins of the strip. Such oblique longitudinalcorrugations are very edective in preventing the hum or singing due tothe action of the strip after the manner of a reed and also inovercoming the noise arising from the buckling action. In practice, Ihave found the best results, in so far as concerns the suppression ofnoise, when the' longitudinal corrugations are arranged at an angle ofabout to the side margins.

As the oblique corrugations do not extend into either the nailing flangeor the bead of the free margin of the strip, they do not interfere withthe pivotal or hinge action of the body of the strip relative to thenailing flange that is necessary to maintain resilient control of thefree edge Of the strip With the closure member. Such corrugationsstiften the body portion against buckling and permit the strip to bemade of a cheaper and lighter gage metal Which can beV formed withlighter and lessexpensive machinery. Such lighter gage metal isresilient enough to maintain contact with the closure member. In addi*tion to being cheaper and easier to make, the lightergage strip does notexert as great resilient pressure against the closure member as astripof heavier gage metal Would and is therefore less liable to cause theclosure membar to stick and bind or be difficult to openand c ose.
